IPC: H01L29/78
Filed: 1991-11-28
Abstract: PURPOSE:To implant the thin film with impurities with low accelerating energy in the manufacturing process of selfalignment type thin film transistor. CONSTITUTION:Semiconductor thin films 2 are pattern-formed on the surface of an insulating substrate 1, a lower layer gate insulating film 3 about 200Angstrom  thick comprising silicon oxide is deposited on the whole surface and then an upper layer gate insulating film 4 comprising silicon nitride about 1600Angstrom  thick is deposited on the whole surface so as to pattern-form a gate electrode 5 on a specific position on the surface of the upper layer insulating film 4. Next, the upper layer gate insulating film 4 is etched away using the gate electrode 5 as a mask and then the semiconductor thin films 2 are implanted with impurities (a) by-an ion implanting device also using the gate electrode 5 as a mask. At this time, the lower layer gate insulating film 3 only about 200Angstrom  thick is formed on the surface of the impurity implanted regions (source-drain regions 2b) so that when phosphorus ions are implanted as the impurities, the semiconductor thin films 2 may be implanted with the impurities with low accelerating energy of about 30KeV.

Title: Drive circuit for liquid crystal display device
Inventor: OOIMA SUSUMU
IPC: H04N5/66
Filed: 1990-11-30
Abstract: PURPOSE:To prevent luminance change due to polarity inversion of a drive signal of a liquid crystal by driving the liquid crystal symmetrically with respect to an opposite electrode level vertically even when a gate-source capacitance of a thin film transistor(TFT) exists. CONSTITUTION:A bias power supply 8 is inserted between a reference level point and an opposite electrode 4. Thus, the ground level is decreased with respect to a drain reference level (0V) being a center level of a drain signal by an opposite electrode level VB, and even when the drain signal is decreased by V0 ( V0') at the OFF state of the TFT, the waveform symmetrical in the vertical direction with respect to the opposite electrode level is formed. Even with presence of the reduction in the level of an AC drive signal due to a capacitor in existence between the gate and the source of the TFT, no luminance change is caused at the polarity inversion of the drive signal of the liquid crystal.

Title: Diaphragm for speaker
Inventor: MAE YUTAKA
IPC: H04R31/00
Filed: 1989-12-28
Abstract: PURPOSE:To control the frequency characteristic without changing the cross sectional shape or the thickness of a diaphragm by applying heat forming to part of resin impregnated woven cloth at a specific heat temperature in the case of the heat press forming and forming a low elastic part to the part of the diaphragm. CONSTITUTION:When a diaphragm 1 is subject to heat press forming, part of a resin impregnated woven cloth is heat-formed in a range of heat temperature of 120-150 deg.C to form a low elastic part 2 to part of the diaphragm. Thus, since the elastic modulus of high strength polyethylene fibers in the low elastic part formed to part of the diaphragm for speaker is reduced to a half the elastic modulus of the high strength polyethylene fibers in the other parts, the propagation speed is reduced in the part. Thus, the propagation of a high frequency signal is controlled.

Title: Ultrasonic atomizer
Inventor: TODA KOJI
IPC: B05B17/06
Filed: 1990-11-30
Abstract: PURPOSE:To enhance atomization efficiency by constituting a piezoelectric vibrator of piezoelectric magnetism and electrodes respectively fixed to both end faces, providing a diaphragm at least at one point in the position covering the aperture of a through-hole or in the through-hole and boring many holes on the diaphragm, thereby forming the diaphragm. CONSTITUTION:The disk-shaped diaphragm 2 is mounted in the position covering the aperture of the through-hole at the bottom end face of the piezoelectric vibrator 1. The diaphragm 2 is made of nickel and is integrally and continuously foxed to the piezoelectric vibrator 1 by an annular fixing part 21. The liquid housed in a liquid housing tank 4 is introduced into the respective holes 40 by capillarity. Since the aperture areas on one side of the holes 40 are larger than the aperture areas on another side, the liquid receives a throttling effect by the holes 40 and flows out to the upper part of the vibrating part 20. Consequently, the liquid flowing out of the holes 40 is atomized by the throttling effect, the coupling vibrations of the vibrating part 20 and the effect of shielding the liquid from the piezoelectric vibrator 1 by a supporting plate 3. The atomization efficiency thereof is thus enhanced.
